Harbor Police say she also stole a violin worth $8,000 from a classroom at Point Loma Nazarene University.

"It worked for her, so she just continued to do what she was comfortable with," said Harbor Police Sgt. Michael Dye.

Crumrine often targeted guests attending conventions at the large hotels. She'd walk in, pick up a suitcase, purse, or briefcase, go into an empty bathroom, pick through it, before leaving, police say. Crumrine is also accused of using the stolen credit cards to buy gift cards, and one time changed into stolen clothes inside one of the hotel bathrooms before walking out.

"If it's a convention you have people moving in and out of rooms," Dye said. "It's an easy target because she would go unnoticed."
